Abstract: PURPOSE:To execute the detection of a safe-ball and an out-ball on the board surface of a pinball game machine by placing a turn-back-like transmitting line, and placing a turn-back- like receiving line which is coupled electromagnetically with the transmitting line and varies an electromagnetic characteristic by approach of a metal, in a face parallel position to the transmitting line. CONSTITUTION:When a current is allowed to flow to a turn-back-like transmitting line 22 and a magnetic field is generated, electromotive force is generated by a mutual induction action in a receiving line 26 coupled electromagnetically with its transmitting line 22. In this case, when such a metal as a pinball B approaches a metal sensor, an eddy current is generated in the direction for negating a magnetic flux caused by the metal sensor on the surface of the metal. In the transmitting line 22, the impedance is varied by influence of its eddy current and a current is varied, and the receiving line 26 varies magnitude of the electromotive force. By detecting this variation, approach of a metal is decided. Plural transmitting lines 22 and receiving lines 26 are provided, and by placing them in the intersecting direction, a detection matrix 20 is constituted, the transmitting line 22 and the receiving line 26 whose electromagnetic characteristic is varied are detected, and a position of the metal is grasped as a coordinate.

Abstract: PURPOSE:To obtain a video signal with stable time base by detecting a phase error of synchronizing signal between an input video signal and that formed by a phase control oscillation system and correcting the phase of the video signal in response to the phase error so as to absorb the tracking error caused at the phase control oscillation system. CONSTITUTION:The phase correction circuit 40 retards a phase of a video signal data 178a outputted by a time DELTA according to a phase error data. Thus, no picture information at a tip 174a of the video signal for a period DELTA from an output 56 of the phase correction circuit 40 and the video signal 170a is outputted in a form the entire video signal data 178a is delayed by the phase DELTA. Thus, the picture information corresponding to the head 174 of the original video signal 170 is missing in the video signal 170a outputted at an output 56 of the phase correction circuit 40, but the carried picture information 178 is kept at a normal timewise position as the signal 178a, that is, the same phase substantially as the picture information 178 of the original video signal 170. Thus, the fluctuation of the time base due to the tracking delay of a phase controlled oscillator PLL 22 is eliminated substantially from the output video signal 170a.
